LIFE-BOAT.

To all whom it may concern:

Be it known that I, HANSON BUD Jovon, a citizen of the United States,and a resident of Seattle, in the county of King and State ofWVashington, have made certain new and useful Improvements inLife-Boats, of which the following is a specification.

This invention relates to life boats.

An object of the present invention is to provide a life boat with noveland removable thwarts allowing a plurality of similarly constructedboats to be nested one within the other to thus occupy little spacewhich is such an important consideration on board a shi 11 furtherobject is to provide a boat including twin keels with connected keelsonsthus dividing the bottom of the boat into three longitudinal sectionsand providing in connection therewith water tight cases disposed withinthe center section providing for the storage of food and drink and whenempty acting as buoyant means.

A further object is to provide a life boat with air cases or tanksextending between the boat frames and aiding in the support of theplanking which rests thereupon.

A further object is to improve generally and enhance the utility of lifeboats and with these and other objects in view which will appear as thedescription proceeds the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, can be made within thescope of what is claimed without departing from the spirit of theinvention.

In the drawings accompanying this specification and forming a partthereof the preferred embodiment of my invention is illustrated, inwhich 2- Figure 1 is a view in side elevation of a life boat embodyingthe features of my invention, portions of the boat being broken away tomore clearly illustrate the internal arrangement. Fig. 2 is a top planview of the foregoing. Fig. 3 is a cross sectional view taken on line3-3 of Fig. 2. Fig. 4 is a View in perspective of one of the removablethwarts.

Referring to the drawings in which similar reference numerals designatecorresponding parts throughout the several views, the life boat includesa hull l of the ordinary Specification of Letters Patent. ApplicationfiledOctober 12, 1914, Serial No. 866,288.

and seaworthy type and is provided with the twin keels 2 to which thekeelsons 3 are secured. The two keelsons divide the bot tom of the hullinto center and side compartments or sections 4 and 5. A plurality oftanks 6 are disposed in the center longitudinally extending compartment4: which tanks are to be kept supplied with food and drink and any otherequipment which may be of use in the case of a ship wreck. The tankswhen empty act in the capacity of buoyant members should the boat becomepartly submerged. The side compartments 5 serve as troughs in which thewater of spray will be collected where it will act as ballast or may beremoved by a suitable bailing device. The sides 7 of the boat hull areprovided with the air tanks 8 which lend the requisite buoyancy andstability to the boat.

It has been found almost impossible on board ship to provide asufiicient number of life boats to accommodate all the passengers due tothe excessive amount of space requisite for such equipment. In view ofthis I provide the life boat with the removable thwarts 9 which allows anumber of boats to be nested one in the other and thus occupycomparatively little space. Each thwart is provided with the hooks 10which are adapted to engage the eyes 11 carried by the boat side wherebythe thwarts will be held securely in place and the boat held andreinforced against bulging. A pair of braces 12 are secured to thethwarts by the hinges 13 and when in their lowered supporting positionconnect strongly with the bight or vertex 14 defined between the bottomand sides of'the boat hull. This will prevent the braces from moving ineither direction when a load is brought to bear thereon.

Strips 15 extend along the sides of the hull and are formed in pairsbetween which extends the canvas curtain or bag 16 in which the sails 17are positioned and held.

hese canvas bags with their contents form buffers or fenders for theprotection of the boat side and at the same time are easily accessibleand may be mounted upon oar masts in a quick and expeditious manner whenthe occasion so arises.

The keels may be provided with rollers 18 and the boat equipped withoars and other auxiliary devices such as a removably portable motor 19should it be so desired. The life boat as thus constructed may beconveniently nested in other life boats possessing the samecharacteristics. The thwarts may be readily and quickly inserted inplace for the accommodation of the passengers and will brace andreinforce the boat in a manner comparing favorably with those of thepermanent type.

Having thus fully described my invention, what I claim is 1. Thecombination with a boat, of a thwart having interlocking engagement atits ends with the sides of the boat and provided on its under side withbraces for engaging the bottom of the boat at the junction of bottomwith the sides.

2. A life boat adapted to be nested within similarly constructed lifeboats comprising a hull, a plurality of thwarts therefor, each of saidthwarts provided with hooks depending from the extremities thereof, eyescarried by the sides of the boat hull adapted to 20 receive said hookstherein, and braces hingedly secured to said thwarts projectingtherebeneath and adapted to engage the b ights included between the boatsides and bottom.

3. A life boat comprising a hull with twin keels, keelsons extendinglongitudinally of the boat bottom and dividing the same into central andSide compartments, buoyant tanks disposed within said centralcompartment adapted to act as containers for provisions, and buoyant airtanks contained in the sides of the boat hull adding buoyancy andstability thereto.
